Abstract


Inner Mongolia Cashmere Goats stud farm from 1995 to 2005 sheep early growth traits and cashmere production traits derived inbred Inner Mongolia Cashmere Goats birth weight , weaning weight , yearling weight , cashmere yield , production the velvet weight, long hair , velvet fine significant inbreeding coefficient greater than 0.0313 , the inbreeding coefficient for each 1% increase in birth weight , weaning weight , yearling weight , cashmere yield were reduced 0.0045kg 0.0391kg 0.0495kg, 2.81g. Derived by comparing the regression model , the model (3) for forecast future generations cashmere yield genetic effects model ( 2) suitable for after forecasting future generations fleece weight genetic effects . Economic weighted the two traits were analyzed to predict offspring genetic effects . Different matching methods analog offspring genetic effects and the average coefficient of inbreeding , the following conclusions : 0-1 integer programming , Applied Mathematics software lingo8.0 of the overall genetic control inbred optional offspring effects to optimize the offspring of higher genetic effects can be obtained and lower inbreeding coefficient increment .
